VCR-GENERATOR.

Application filed May 19, 1920.

To all whom it may concern:

Be it known that I, HENRY a citizen of the United States, residin at Quincy, in the county of Adams and tate of Illinois, have invented certain new and useful Improvements in Vapor-Generators, of which the following is a specification.

My invention relates to an improvement in vapor generators.

I-Ieretofore it has been customary touse some such material as abestos in the vaporizing and lightin rings of wickless oil burners. In fact,'wit very fewexceptions,'this has been the invarable practice. In one of the exceptions, the burner is made for cocking purposes only, where a very large flame is used substantially all the time, and for this reason it is possible to maintain the heat after the vapor is once generated Without the assistance of a vaporizing ring.

In my burners, and especially in the smaller sizes, the generatingheat can not be maintained without a vaporizing ring of some kind, and by careful experiment .I.

M. SHEER,

have found that the old type of asbestos ring needs frequent renewing, and is a source of.

considerable trouble to the operator.

The purpose of my present invention is to not only overcome-the objections previously encountered in the use of Wickless burners, but also my object is to attain the highest efiiciency and economy, and this I accomplish by the use of a notched band or ring of high heat conductivity in the oil groove in the base of the burner. While this band or ring might be variously formed, and it is the purpose of this patent to'cover my invention broadly, still my experiments have led me to believe that the greatest success, efliciency and economy are attained by the use of a notched band or ring for the double purpose of increasing the heating surface and permitting the va r to burn freely in the notches, and in th1s way raiseit to a high degree of temperature. In its present chosen form, both the notches and the points are rounded, for reasons that will be explained, chief of which are, first, quicker and more satisfactory evaporation and vaporizing; and, second, in the chosen form, the rings or hands are cut from the sheet of material absolutely without waste of material.

In the accompanying drawings:

The numeral 1 represents a typical form of grooved burner base. This, of course, 1s sub ect to variation as to size, shape, depth, or even width, and hence capacity for liquid fuel.

The numeral 2 indicates my improved ring ,or band. This is shown in the draw ings in the preferred form. To attain the hlghest efiiciency, a metal of high heat conductivity should be used. Copper would probably be the best, but I have decided in most instances to use low brass, which con." tains quite a percentage of copper. Cornmon sheet-iron, of course, could be used,

although it lacks somewhat in heat conductivity. /Vhile certain metals are obviously more suitable than others, I do not care to be confined to the use of any particular metal. I 1

In form, this ring or band 2 is provided with notches 3, on opposite edges, thereby forming prongs rounded as at a and 5 both at their outer and inner ends. There is a reason for this particular construction, and while I appreciate that the ring or band might take other forms, experiment thus far has proven the wisdom of this particular selection.

My new principle of vaporizing consists of this notched metal band of high heat conductivity placed in the 'oil groove 6 of the base of the burner 1. This bender ring is notched for the double purpose of increasing the heating surface, and of permitting the vapor to burn freely in the notches, and in this way bring it to a high temperature.

The metal em loyed being of high heat convaporize, in fact would flash up before it i could find its way entirely around theioil groove 6 and the flame would burn high Whereoil enters burner. By reason of being rounded on the ends, the prpngs or notches of the band increase the heating surface as the depth of oil increase in the oil groove of the burner. If these prongs were left the full width at the bottom, where they rest on the bottom of the groove, it would be impossible to burn asmall flame, because the oil would become vaporized before it could travel all the way around in the groove 6. The ends of the prongs are rounded, so as to provide the proper evaporating and heating surface for every size flame that may be required. In other words, the vaporizer must have provision for. the oil to flow all the way around in the oil groove of the burner.' The amount of metal in contact with the oil must be in proportion to the amount of oil to be vaporized. This is why it was found desirable, if not necessary, to cut notches in the vaporizer, thus permitting the oil to flow freely all around the oil groove in the oil burner, and as the depth of the oil increased, the vaporizing surface of the metal would increase in proportion.

With a very light film of oil in the bottom of the oil groove in the burner, there is very little ofthe metalof the oil ring in contact. This is because the ends 4 of the rongs are rounded. If the ends were flat, t ey would have a tendency to vaporize too much of the oil before it could flow all the way around theoil groove in the burner.- As a consequence, the flame would burn up high on the side of the burner, where the oil enters. On the other hand, if the prongs or lobes were made pointed on the ends like a sawtooth, they would not provide sufficient evaporating surface, and the oil in the groove 6 would be permitted to get too deep, and then there would be a possibility of flooding in consequence.

The radiating surface of the generator must be employed to carry the heat down to the lower prongs 4:, and keep them sufliciently hot to vaporize the oil. The width of my improved vaporizer should conform with the depth of the oil groove in the burner. Some burners are quite deep; others, shallow, so the width of the vaporizer should be governed accordingly.

The burner, of course, must be started to begin with by using gasolene or alcohol, but with this notched ring it is heated in a few minutes, and after vapor is once generated there is no surplus oil in the groove at any time, in fact it is practically all vaporedge of two rings or bands. This is of con siderable importance from an economical manufacturing standpoint. v

I. claim:

1. The combination with the oil groove of a burner, of a metal vaporizing ring having supporting prongs resting inthe bottom of the groove and staggered rounded prongs on the opposite edge. u

2. The combination with the oil groove of a burner, of a metal vaporizing ring or band removably arranged therein having spaced supporting prongs rounded at their ends formed on the lower edge thereof adapted to enter the oil groove, whereby to increase the heating surface as'the depth of the oil increases.

3. The combination with the oil groove of a burner, of a metal vaporizing ring removably supported in the oil oove, said ring being provided with a series of upper and lower prongs.

4. The combination with an oil burner cup, of a vaporizer made solely of metal substantially conforming in size and form to the cup, and adapted to rest removably therein, said vaporizer having openings at frequent intervals, whereby to permit the free passage of oil therethrough in either direction and to both sides of the vaporizer.

5. The combination .with an oil burner cup, of a vaporizer made solely of metal substantially conforming in size and form to the cup, and adapted to rest removably therein, said vaporizerhaving openings at frequent intervals with (respect to the burner cup, whereby to permit the free passage of oil therethrough in either direction and to both sides of the vaporizer.
